bash: `printf` supports `\e` just like `echo -e` does

Posted by jpluimers on 2017/11/07

Learned a few things when modifying https://github.com/gkotian/gautam_linux/blob/master/scripts/colours.sh

Note: `printf` supports emitting `ESC` (ASCII character `\033` aka `27` aka `0x1B`)as `\e` the same way that `echo` does

https://linux.die.net/man/1/printf
https://linux.die.net/man/1/echo

Format strings are at https://linux.die.net/man/3/printf
%-10s means left adjusted (aligned) string of length 10

I was investigating how the colour definitions on my OpenSuSE system actually work internally so I added some extra output: ${TYPE} and ${COLOUR}.

Long read about Unicode: You, Me And The Emoji: Character Sets, Encoding And Emoji – Smashing Magazine

Posted by jpluimers on 2017/11/07

A well worth long rad:

We all recognize emoji. They’ve become the global pop stars of digital communication. But what are they, technically speaking? And what might we learn by taking a closer look at these images, characters, pictographs… whatever they are 🤔 (Thinking Face). We will dig deep to learn about how these thingamajigs work. Please note: Depending on your browser, you may not be able to see all emoji featured in this article (especially the Tifinagh characters). Also, different platforms vary in how they display emoji as well. That’s why the article always provides textual alternatives. Don’t let it discourage you from reading though! Now, let’s start with a seemingly simple question. What are emoji?
